Viruses need to deliver its DNA or RNA genome into living host cells in order to reproduce. Naturally reproduction and spreading from host to host is the optimal environment for a virus. When a virus is outside of a living cell, it stops metabolizing and cannot reproduce. Sometimes viruses that are fought off by the human immune system become metabolically inert or dormant in a body (which is why you are immune but always carry viruses).
I'm not sure what people think about the "thought process" of a virus, but survival is key. Viruses can adapt, mutate, jump hosts, etc. in order to survive. They may not have a thought process like a human mind, but they have a survival "instinct" unlike most anything in nature.
The major component we are all trying to figure out is whether herd immunity or a vaccine can stave off Covid-19. Right now the R Naught factor (listen to Dewine say we went from 2-1 to 1-1...this is R Naught) has gone down in Ohio (2-1 to 1-1). This means the mutation is weakening as it cannot spread as frequently. Lends the thought process to both experts and the layperson that herd immunity is effective and would be a far better resource to use by opening up than waiting on our country to go to waste.
